Ctirad, Natural monument in Prague 5, Czech Republic

Ctirad is a natural monument on the northern edge of the Děvín hill above Zlíchov in Prague 5, covering rocky and steppe vegetation, a road cutting near Dívčí Hrady and the abandoned Bílá skála quarry east below the railway. It protects Silurian and Devonian rock exposures of the Barrandien with fossil sites known since the time of Joachim Barrand.

Ctirad was declared a protected natural monument to safeguard the Silurian and Devonian rock exposures of the Barrandien, whose supporting geological profiles and fossil sites have been known since the era of Joachim Barrand. The area is administered by the Prague City Hall.

The name Ctirad comes from a legendary figure of Czech mythology, but the sources document the site's cultural value through geology: fossil beds at the Silurian and Devonian outcrops of Barrandien have been known since the era of Joachim Barrand. The northern slope facing the Konvářka farmstead keeps a flowering stand of Brachypodium pinnatum with the endangered Gentianopsis ciliata.

The monument lies on the northern edge of the Děvín hill above Zlíchov, and its parts are reached on foot: the road cutting by Dívčí Hrady and the abandoned Bílá skála quarry east below the railway. The terrain is rocky and steep, so wear sturdy shoes.

The northern slope facing the Konvářka farmstead keeps a flowering stand of Brachypodium pinnatum, where the endangered Gentianopsis ciliata grows. The site is also a refuge for small invertebrates, and the common lizard (Lacerta agilis) still lives here.
